A complete kit that includes the Monster MM3 mill and hopper, with or without the extension. Monster mills are known for being great quality, top of the line, homebrewing mills. With all the great features of the already popular MM-2, and the addition of a third roller, you'll be able to achieve the best crush around, at a higher throughput speed. The MM-3 crushes all your grain twice, with one pass through the mill. It starts with a preliminary crush through the initial fixed gap between the top two rollers, and then ends with a pass through the second gap between the drive roller, and the bottom third roller. The initial pass slightly flattens the grain, and gets it ready for the next crush, that breaks apart the grains and loosens the starch with minimal husk damage.

The MM-3 consists of a 6061 aluminum block frame with three 6" long steel rollers riding on SAE 841 oil impregnated bronze bushings. We use a superior grade of steel that is much harder than what is found on most comparable products and should last almost twice as long. The drive shaft, and all the axles are integral to the roller rather than screwed into the ends. This makes it fine to drive the mill clockwise, or counter-clockwise. All the axles are 3/8", with minimal freeplay in the bushings.

One knurled steel roller is driven by a standard electric drill (not included) to feed the grain through the initial fixed gap of approximately .060", and then through the adjustable secondary gap and crush the grist. Both ends of the non-driven top idler roller ride in bronze bushings that are pressed into the frames, while the second idler roller rides in bushings that are offset mounted in an adjustable knob. The knob is held in a fixed position by a set-screw that you can loosen to adjust the mill. This system provides an adjustment range of .065". The knobs are made from 303 stainless steel for excellent durability, and are larger in diameter than the competition, as well as knurled for a positive grip. They've also added a groove in our newest design knobs with a matching rounded head on the thumbscrew that allows for a much better grip on the knob to avoid gap changes while milling, and also providing knob retention.

These Packages come complete with a Base, 3 Roller Monster Mill Body, and a Hopper. Choose whether to include the Hopper Extension, which upgrades Hopper capacity to a huge 39 lb!

Features:

Three six-inch steel rollers form two gaps, a preliminary fixed gap of approx .060", and a fully adjustable secondary gap.

Dual eccentric adjusters: 0 to .065" secondary gap - built from STAINLESS STEEL for no galling

I want to get into all grain brewing soon, and I generall like to buy good quality, long lasting equipment even if it's a little more expensive. Read a lot of reviews, all said that this is the best home brewer's grain mill on the market.

BEST ANSWER:Yes, but the mill and the motor don't have the same size shafts. So, you'll need to buy a flexible shaft coupling hub that'll allow you to match the two different size shafts. McMaster Carr sells them online. Their part number is 6408k14. You'll need two, one with 3/8" diameter and one with 12mm diameter. Then you'll need part 6408k75 to hold them together. Hope that helps.

I wish I could answer that for you but I've had trouble getting the shaft coupler to stop slipping ever since I got it and when I reached out to Brewmaster they were no help. The motor sure seems good in concept but I have trouble figuring out how it's compatible with anything so far :/ that said the mail I attempted to hook into is a three Roller Mill but not a monster brand, again my concern would be with a design in general not so much which Mill it should be connected to

My milling set up includes this motor and mill mounted on the underside of a stainless table. It works very well! The bottom of the hopper fits through a hole cut in the table and the milled grain drops through a 7gal. pail lid bolted to the table. No dust. Mill and motor are very quiet. Pics and video available.

You should be able to. The monster mill has a 9.525 mm (3/8") shaft. The malt muncher motor comes with a coupler for 10 and 12 mm shafts. I think you should be able to tighten it enough to make up the 0.5 mm. Otherwise you can find different size couplers online. Shaft couplers are pretty common.

I'm brewing with about 20-25 lbs of grain in each batch. I typically have to refill the hopper 3 times. If you're doing 10+ gallon batches it would be a good investment to make. But keep in mind the capacity of the bucket you're grinding into as well. I typically use 2 separate buckets to catch my grindings. 1 moreover bucket and 1 Home Depot bucket. Hope this helps!

Works like a charm! (Slight height difference in the motor & the MM3 even with the included bamboo board, fixed with what I had though) Love this thing. You have to adjust the gap with the hopper off. Not that bad since I won’t change the gap frequently at all. Assembly was easy and it even with the motor at 200rpm it still chews through grain quickly with a nice crush.

Probably the best investment so far, leading up to this point I have been having a lot of trouble with undershooting gravities, beersmith showing mash efficiencies of 51, after buying this mill and tuning the crush, I now hit 81% mash efficiency and my target gravities, giving me more confidence! Not hard to put together, tho the instructions are lacking if I am to be honest.

Some reviewers have complained of the level of difficulty in putting the hopper together. Didn't really have any difficulty with the assembly. #1 Phillips and a 11/32 socket were the only tools needed to get the hopper together. The included exploded diagram shows how it all fits together. Just take your time . Screw heads on the outside, nuts on the inside.While it may not bother some, consider running a file along the edges of the hopper pieces to smooth out some rough spots - nothing serious, just a few swipes with a mill file. (It's just stamped sheet metal.)The mill itself comes assembled. Check the Monster Mill website for a very thorough tutorial on mounting the mill, adjusting the side blocks for proper operation. It also shows how to adjust the rollers for the desired gap. The visual in that video is much easier to follow than the printed instructions.Before putting the hopper in place, set the gap, check end play and how freely the rollers spin. Again, all in that Monster Mill video and probably all over You Tube. I also took an old paint brush with stiff bristles to the rollers to remove metal flecks still left over from the machining process.Good purchase. Very happy with it. Would do it again, but probably won't need to do so for a long, long time.

My only complaint is that the second page of instructions (for putting the hopper together) was hidden under the packing peanuts in the hopper box. It was straightforward enough to put together without them though. The mill works great and replaces my old Barley Crusher. I get a more consistent crush with better separation of the grist from the husks. About the same efficiency so far, we'll see if I decide to adjust the gap later. The second roller puts quite a bit more torque on the drill-brace it against your knee or something to avoid a sudden twist of your wrist when the third roller catches.

I looked at several other mills before deciding on th MM-3, most were a lot less money. I was impressed by the design features and thrilled I could actually buy an American product actually made here. I ran a pound and a half of barley at different setting to clean it prior to use and to see what the crush looked like. I got what I’d hoped for: everything from barely cracked to near flour. Did I need this much mill? Of course! It’s amazing and I love it, and I won’t likely ever wear it out. I got the hopper extension that expands capacity to 38 lbs. too. When SWMBO gives the green light, go for it!Tried to drive it with my 18v cordless drill and it just wasn’t enough to get through the 18 lbs I needed to brew a few days later. At .025 gap, it bound up-this was wheat BTW. .032 was better, but I don’t want to run it twice and it drained the battery quick. Wider gaps might be more forgiving, but I’m playing with BIAB, so tighter gaps are a given. Bought a 1/2” keyed chuck drill from Harbor Freight for 30.00, and it ripped through my grain bill in no time. More torque to drive this mill is a definitely a good thing.Others have mentioned what a pain it is to change the gap. I experimented with feeler gauges at different settings and marked and labeled them on the frame and adjusting knobs, so resetting now is two thumb screws and the knobs. No sweat. I wish the base it comes with was bigger. I’d like to be able to support the drill on it, and maybe mount a speed control for the drill, but this a minor pick. If you love quality tools that will probably outlive you, buy this mill!

Great mill - used this to replace the smaller 2-roller mill, and once the gap was set, this new 3-roller eats grain like a monster - what took 3-7 minutes to grind before now takes about a minute. Also, efficiency went up 5-8 points (from mid-80's to lower 90's)! Don't skimp on the motor; get a 1/2" drill motor to drive this killer, 3/8" won't cut it.

I never had a mill before so I can't compare it to others. I'll just say I'm very satisfied with it. The standard 7# hopper easily holds 10# to 11# of grain. You do need a fairly heavy duty drill to drive it and I can't imagine grinding 10# of grain by hand with it.

If I had any complaints, it would be the attachment method of the hopper to the mill. You must entirely remove the roller position locking bolts in order to remove the hopper for mill adjustment. It seems like it would be easy enough to make the holes in the attachment assembly into slots open to the base so simply loosening the bolts slightly would permit removal. But that is very minor issue since once you've achieved the crush you want there is little need to readjust.

50lbs of grain without any issues. I did notice the hopper comes with 2 little triangle shaped pieces that fit inside near the rollers to guide the grain, but I think they are for Mills with shorter rollers to push the grain into the center. With the MM3 the rollers are wide enough that these pieces are not needed. When those were attached I was having jamming issues so I took them out and didn't have any further issues.

Have only used the mill one time, but it worked great and powered through 50lbs of grain easily.

I had been contemplating purchasing a mill for a couple of years. I had always received perfectly milled grain from my normal supplier, Rebel, but alas they are no more. With my replacement supplier, my efficiency declined dramatically. Finally, even when I had asked that the grain be milled finer, it came not milled at all. Thus my hand was forced.

I had been looking at the Monster Mill 3 for some time, but price was pretty dear. I didn't have sufficient incentive to buy it until now. It does a helluva job. I had to buy a new drill to drive it. I'm afraid my 40+ year old B&D just didn't have the torque.

I set the mill at .043. Supposedly the factory setting is .045, but I ran a couple of pounds through it out of the box and it came pretty close to making flour. See the utube videos for making adjustments. At .043 I hit almost 86% efficiency, while my previous normal was 83. I'll probably dial it back to .045 before the next batch.

Putting this together and adjusting it isn't necessarily easy. I bought it with the standard 7 pound hopper and the base. I probably spent a couple of hours all told getting it properly set up and adjusted. Once adjusted and set up, it will run through the hopper load in seconds. I thought I would probably be adding noticeable time to brew prep, but it is negligible.

I'll say I'm not real crazy about the hopper construction and the way it attaches to the mill. As designed and built you can't adjust the mill without removing the hopper. Removing the hopper requires removing the mill adjustment lock bolts and 4 attachment bolts. Kind of a PITA. The hopper is 4 pieces (well, actually 6 but two are small end pieces) of sheet metal. There are a lot of machine screws, washers and locking nuts. If the hopper were two or 4 pieces there could be a lot fewer fasteners. I assume the design is to be more shipping friendly.

I can't speak to how this mill compares to others, but it seemed like the best in class when I started looking and still seemed so, so I bought it. I'm very satisfied so far. Morebeer had the best price by a significant factor when I was looking. Shipping was fast and it arrived in fine shape.

So, if you can afford it/justify the price, and you are reasonably handy, buy it. I don't think you'll be disappointed.

Awesome product! Well built sturdy and strong, mills grain very well for improved brewing efficiency. Although, it can jam up if you don't spin the rollers before filling the hopper or you initially dump grain in too fast. Not a big deal, just dump the grain out of the hopper and slowly pour it again to "prime" and then refill the hopper as it's milling.
